The NicheHash crypto mining marketplace contains the majority of the hashpower on the Dash network. A concerned Reddit user raised the alarm today.
Dash has a total of almost 1,900 Terrhashes per second at time of writing. Meanwhile, NiceHash is responsible for more than 1,000 TH/s across over 25,000 miners.
Analysis by the concerned Reddit user found that three of the top addresses over the last few thousand Dash blocks are controlled by the same entity. They write:
This particular transaction has three of the four top addresses as inputs meaning one entity controls all three. These three alone gather 53% and more. You can also see this started 6 months ago/around September last year, and I think the fourth unknown pool also belongs to this entity yet it is seperated on the blockchain. It started to gather a lot of hash at the same time.
